POWER: 

The Dragino HE is the core module of Yun Shield. The HE module requires around 200ma current 

when in full load, so it is powered by the Arduino 

VIN

 pins to avoid overheated in the Arduino 

onboard 5v LDO. So when Yun shield is in used, the Arduino board should be powered by DC port 

instead of USB port. The DC input can be 

7v ~ 15v.
